Daisley (Dailey) of Cape Breton Island

I am looking for information on my great Grandmother, Susan J. Daisley(Dailey?) born March 1854 and emigrated to the U.S. in 1865. United States Census records show that she and her parents were born in Cape Burton Island Canada( I assume this was a spelling error) I do remember my mother mentioning Antigonish as a possible place for relatives also. Does anyone have a suggestion as to where I could research for further information? I do not have her parents names. She later married a Thomas Quinn and lived in Weymouth, Massachusetts.
